Merino Challenge Socks - Trail Cuff

BEST-IN-CLASS WOOL SOCKS MANUFACTURED IN THE USA

We put our feet through hell, so our socks must meet the highest standards—no blisters, no friction where the sock meets the shoe.

Enter the Merino Wool Challenge Sock - Trail Cuff. Built for short rucks or sandbag workouts in your driveway, these socks won’t wear thin or lose shape. They’ll keep your feet dry and, even after days of use, they don’t stink. They are an ideal match with the Mackall All-Terrain Rucking Shoes (trust us, you won’t regret it).

They’re unconditionally backed by our Scars Lifetime Guarantee and proudly made in the USA.

Socks are final sale and not eligible for returns or exchanges.
